Boboro lore (Patreon)

Born into a family of devil hunters, Boboro was a prodigy at hunting. Thing is, he didn't like doing it and honestly preferred to just relax. That is until his sister was attacked by a group of devils which resulted in her being permanently changed. From that point forward, he decided to become the world's top devil hunter, only the way he hunted them was different.

He didn't only fight them, but broke their spirits as much as he could. Eventually, there was a truce made between devils and devil hunters which outlawed hunting devils and also outlawed devils tormenting hunters. 

Despite this, Boboro found alternative means of tormenting devils that annoyed him. Ones that didn't exactly involve fighting them.
